Rizzi Studio combines modern and classic architecture with their spiral staircases.

The self-supporting staircases are crafted from concrete with individual modules prefabricated and then combined into a classical-looking spiral staircase. Each module is shipped to the home then assembled on-site. This way of building a spiral staircase is not traditional but cuts down on installation time.

The stairs can be finished in several different materials including stainless steel, ceramic, marble, wood, and resin.
